摘要
为实现汽车与摩托车碰撞事故的仿真再现分析,基于经典动力学理论,构建事故碰撞动力学模型及摩托车翻滚运动轨迹模型,初步探讨碰撞事故的人车分离问题。针对事故案例,分别利用PC-Crash软件与构建的碰撞动力学模型及轨迹模型进行再现分析,对比轨迹再现结果和现场残留痕迹。结果表明:汽车的二维速度、角速度及摩托车的三维翻滚角速度与PC-Crash软件分析结果相接近;汽车与摩托车运动轨迹的再现与事故现场痕迹相符合。
In order to realize simulation and reconstruction analysis of collision accidents between automobile and motorcycle,a collision dynamics model and trajectory model of motorcycle’s rollover movement were constructed based on theory of classical dynamics. The problem of separation of person and motorcycle was discussed preliminarily. Using the collision dynamics model,trajectory model and PC-Crash respectively,a real accident case was reconstructed and analyzed. A comparative study between reconstruction analysis results and marks remained in the accident scene was conducted. The results show that automobile’s 2D velocities,angular velocity and motorcycle’s 3D rolling angular velocity calculated by the model are similar with the results of PC-Crash,and that movement trajectories of two vehicles are consistent with marks remained in scene.
